Summary & Overview
HCPCS P9041: Infusion of Albumin (Human) 5% 50 ml
HCPCS Level II code P9041 represents the infusion of human albumin 5% in a 50 ml vial, a commonly used plasma expander in acute care. Nationally, albumin infusions play a role in treating hypovolemia, hypoalbuminemia in specific clinical contexts, and as adjunctive therapy in select surgical, critical care, and nephrotic syndrome scenarios. Standardized billing for this supply is important for hospital and outpatient infusion accounting and for payer coverage determinations.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, common billing considerations, and payer coverage scope. The publication outlines benchmark concepts for supply-level HCPCS billing, highlights policy considerations relevant to coverage (medical necessity and documentation expectations), and summarizes where to locate payer-specific coverage rules.
This summary provides clinicians, billing staff, and policy teams with a practical reference to understand what P9041 denotes, why it matters for reimbursement and clinical supply management, and what to review when preparing claims or assessing coverage policies. Data not available in the input is flagged where applicable.

Clinical & Coding Specifications
Clinical Context
A typical patient is a hospitalized adult with hypoalbuminemia from acute illness such as sepsis, major trauma, or decompensated cirrhosis who requires plasma volume expansion or albumin replacement. The clinician orders P9041 for administration of a 5% human albumin solution in a 50 mL vial when small-volume albumin dosing is indicated (for example, bridging during paracentesis or targeted oncotic support). The workflow includes nursing verification of the order, consent per facility policy if required, review of indications and allergies, IV access confirmation, administration per institutional infusion protocol (rate and monitoring), documentation of lot and vial numbers, and monitoring for infusion reactions. Post-infusion assessment includes vital signs, fluid balance evaluation, and adjustment of ongoing diuretics or vasopressors as clinically indicated.
